Giant J (Osborn) Wave due to Bonsai Abuse: Comments on Clinical Practice
BACKGROUND Osborn wave, typically associated with hypothermia, is currently referred to as one of the J wave syndromes due to its clinical potential to develop lethal cardiac arrhythmia; it may rarely be observed in a non-hypothermic setting such as cannabis abuse. CASE REPORT In this paper, we presented two young cases who presented to the emergency services with unconsciousness, drowsiness,...
متن کاملECG Changes Due to Hypothermia Developed After Drowning: Case Report
Drowning is one of the fatal accidents frequently encountered during the summer and is the most common cause of accidental death in the world. Anoxia, hypothermia, and metabolic acidosis are mainly responsible for morbidty. Cardiovascular effects may occur secondary to hypoxia and hypothermia. Atrial fibrillation, sinus dysrhythmias (rarely requiring treatment), and, in serious cases, ventricul...
متن کاملCase of Recurrent Ventricular Fibrillations with Osborn Wave Developed during Therapeutic Hypothermia
Therapeutic hypothermia (TH) has been used to protect neurological functions in cardiac arrest patient. Although Osborn wave is not pathognomonic of hypothermia, it is a well-known electrocardiogram finding of hypothermic patients. The cellular and ionic mechanisms of the Osborn wave have been suggested, and its relationship to tachyarrhythmias, such as ventricular tachycardia and ventricular f...
متن کاملA case of hypothermia with significant Osborn Wave: a forgotten electrocardiographic finding
Hypothermia is generally defined as the body's internal temperature below 35 °C. Hypothermia is classified as primer and secondary hypothermia according to its mechanism, and as mild (32 to 35 °C), moderate (32-28 °C) and severe (below 28°C) hypothermia according to body temperature. The characteristic electrocardiographic finding of the hypothermia is the Osborn (j) wave, which is manifested a...
متن کاملOsborn waves in a hypothermic patient
A 56-year-old man presented with hypothermia (rectal temperature of 30.18C) and hypotension after being found by emergency medical services (EMS) on his basement floor. A 12-lead electrocardiogram (ECG) revealed normal sinus rhythm with a rate of 62 bpm, right bundle branch block, prolonged QT interval (QTc of 564 ms), wide QRS (110 ms), and a prominent J wave in the precordial leads (Fig. 1). ...
